Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Figure 1 to Figure 5 An embodiment of the mechanical interlocking device for the pressure vessel door of the present invention is shown. The mechanical interlocking device for the pressure vessel door in this embodiment includes an air intake pipeline 5, an interlocking valve 4, and a valve for restricting the opening of the door 1. Pneumatic limiter 2, the air intake line 5 is connected with the pneumatic limiter 2 through the interlock valve 4, and the interlock valve 4 is provided with a valve that can deform and open the interlock valve 4 after being subjected to the pressure in the pressure vessel 3 Elastic diaphragm 44. Wherein, the door 1 can be, for example, a common quick-opening translation door, and the pneumatic limiter 2 can be, for example, a cylinder, etc., and the cylinder is installed on one side of the trans...

Abstract

The invention discloses a mechanical interlocking device for a pressure vessel door. The mechanical interlocking device comprises an air inlet pipeline, an interlocking valve and a pneumatic limitingpiece used for limiting opening of the door, the air inlet pipeline is connected with the pneumatic limiting piece through the interlocking valve, and the interlocking valve is provided with an elastic membrane which can deform to open the interlocking valve after being subjected to pressure in a pressure vessel. According to an interlocking method of the mechanical interlocking device for the pressure vessel door, when the pressure of the pressure vessel is insufficient to enable the elastic membrane to deform to open the interlocking valve, the air inlet pipeline cannot provide air for the pneumatic limiting piece, and the door can be opened; and when the pressure of the pressure vessel enables the elastic membrane to deform to open the interlocking valve, the air inlet pipeline can provide air for the pneumatic limiting piece, the pneumatic limiting piece acts, and the door cannot be opened. The pharmaceutical equipment comprises the pressure vessel and the door, and further comprises the mechanical interlocking device for the pressure vessel door. The mechanical interlocking device is not affected by power failures and faults of electronic components, and is safe and reliable.

Description

technical field [0001] The invention relates to food and medicine packaging machinery, in particular to a mechanical interlocking device for a pressure vessel door and pharmaceutical equipment. Background technique [0002] For pressure vessels with quick-opening doors such as sterilization cabinets, accidents caused by quick-opening doors of pressure vessels (positive pressure) occur from time to time, which poses a very large risk to the personal safety of relevant personnel. At present, the simple interlocking device of the automatic control system cannot effectively identify the risk under the condition of power failure or the failure of electronic components. In addition, interlocking pressure relief during door opening may also accidentally injure people due to excessive door opening pressure. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a safe and reliable...
